Description
Original diagnose after Woodward (1932) p. 476 [2608]: Type.-In the type-specimen, which is shown of about one-third the natural size in PI. XVIII., the anterior half of the fish is exposed from below, crushed but not much distorted. Fragments have been removed to the counterpart, which seems to be lost. Other fish-remains occur on the same slab, notably some examples of the small Charitosomnus lineolatus, of which one lies across the rostrum just behind its middle. Specific characters.-Rostrum at least 15 cm. in length, regularly tapering, and less than half as wide distally as proximally. Teeth of the mouth with an erect principal cone and a single pair of large, slightly divergent, lateral denticles; base of each tumid and marked with delicate vertical striae. Branchial region slightly longer than wide. Depth of pectoral fin about three times width of the pectoral arch, its gently curved anterior border with a row or cluster of pointed dermal tubercles on stellate bases; similar dermal tubercles sparsely scattered over part of the membrane of the same fin.
